Homologous series Flashcards
What is a homologous series
A family of compounds with the same general formula and simile chemical properties
What are hydrocarbons
Compounds containing only hydrogen and carbon atoms
What compounds are described as saturated
Compounds only containing single carbon to carbon bonds
What compounds are described as unsaturated
Compounds that contain at least one carbon to carbon double bond
What is the test for unsaturated compounds
Unsaturated compounds decolourise bromine solution quickly
What are isomers
Compounds with the same molecular formula but different structural formulas
